CONVERTIBLE DRILL AND WRENCH.

SPECIFICATION forming part of Letters Patent No. 465,626, dated December22, 1891.

Application filed March 31, 1891. Serial No. 387,145. (No model.)

To aZZ whom it may concern:

Be it known that LJOHN WATERMAN, a citizen of the United States,residing at Villisca, in the county of Montgomery and State of Iowa,have invented certain new and useful Improvements in Convertible Drillsand renches and I do hereby declare the following to be a full, clear,and exact description of the invention, such as will enable othersskilled in the art to which it appertains to make and use the same.

My invention relates to improvements in convertible drills and wrenchesespecially adapted for use in drilling railway-rails and loosening ortightening bolt-nuts or taps on the rails.

The object of my invention is to provide a simple and compact machinefor drilling railway-rails, which machine can be readily changed toadapt it for loosening or tightening nuts on the rails.

With these ends in view my invention consists of a single upright orstandard suitably pivoted in one end of ahorizontal main frame, a shaftextending vertically through the cen ter of said standard, which shaftis provided with a crank and handles on its upper end and a gear-wheelon its lower end. Secured in the main frame and projecting therefrom isa drill-stock, which is provided with a gearwheel which meshes with thegear-wheel on the upright-shaft, and in the other end of the main frameis a supplemental frame,in which is secureda feed-screw which operatesto feed the drill forward and keep it in position for operatingproperly. On the lower end of the upright shaft, above the gear-wheelthereon, is an eccentric disk which engages with a lever, and this leverhas two pawls on its end to engage with ratchet-wheels on the feedscrew,by means of which the said feed-screw is revolved and the drill advancedor returned. Pivoted on the forward part of the upright is a bifurcatedholding-arm which insures a good contact with the rail and holds themachine steady. To further hold the upright in a firm position, Iprovide a foldable brace,

one end of which is fastened to the upright and the other end to therear end of the main frame. Pivotally secured on the rear end of themain frame is a rest which has its basepiece projecting at either end toform handles for carrying the machine or steps to hold it steadily inposition with the feet, as described.

My invention further consists in providing two arms or hooks on thefront of the frame instead of the single bifurcated arm and pivoting thesame to bars secured in guides or keepers on either side of the mainframe. The foldable brace is also provided with a bifurcated lowerportion, and these bifurcated arms are pivotally secured in the rear endof the frame. The extreme ends of these arms are bent upwardly andloosely secured to the rods, so that when the brace is bent and thestandard lowered the ends of the bifurcated arms will move the side rodslengthwise and thus loosen the holding-arms on the rail.

My invention further consists of the peculiar construction andarrangement of parts, as will more fully appear hereinafter.

To enable others to understand my invention, I have illustrated the samein the accompanying drawings, in which Figure I is a side elevation ofmy improved machine, partly broken away, to show the working mechanism.Fig. II is a view show ing the upright in a folded position and thedrill-stock provided with a wrench for use in tightening or looseningbolts. Fig.'III is a rear view of my machine. Fig. IV is a sectionalelevation taken on the line 00 a; of Fig. III. Figs. Vand VI areelevations showing modified constructions of my invention.

Referring to the drawings, in which like numerals of reference denotecorresponding parts in all the figures, l. designates the upright orstandard, which is preferably made of wood, and is mounted on a plate 2,having the downwardly-extending ends 3 3,an.d this upright is braced byrods 4 l, secured to the plate 2 and the upright on either side of thelatter. Extending through the center of the upright is a shaft 5,which'has gear-wheels 6 7 on either end thereof. The upper gear 6 mesheswith another gear-wheel 8 on a shaft 9, which is journaled in bearingsin the upwardly-projecting ends of the plate 10, secured on the top ofthe upright 1. The shaft 9 is provided with suitable cranks 11, and whenthese are turned the shaft 5 is revolved.

Fitted on this shaft 5, just above the gear 1 is a cam 12, whichrevolves with the shaft, for a purpose hereinafter described. Thedownwardly-extending ends 3 3 of the plate 2 are secured to shortmetallic strips 12 12, which extend at right angles to the ends 3 3,andare secured to the sides of the main frame 13 about the center thereof.Suitably mounted in this frame is a drill-stock 14:, which projectsbeyond the front of the frame, and is adapted to receive a drill orwrench, as desired. This drill-stock is provided with a gear-wheel 15just inside the frame 13,which meshes with the gear 7, and by means ofwhich the drill is operated. The strips 12 12 are of such length thatwhen the upright is in a vertical position the gears and 7 will bebrought into a proper engagement, and in order to provide a firm basefor the upright I arrange an upwardly-extending plate 16 on the front ofthe frame 13, upon which a small projecting plate 17 on the upright 1 isarranged to rest. This main frame 13 is provided with a resting-plate 18on the forward end thereof and another base-plate 19 on the rear end ofthe frame which has the projecting standards 20 pivoted on a shaft 21.By means of this pivoted plate I provide a suitable base for the machinewhen it is in operation, and when it is desired to move the same thisbase can be turnedup over the end of the frame and the projecting endswill then form handles by which the machine can be carried.

Secured to the shaft 21 is a foldable bracerod 22, which is connected tothe upper portion of the upright, and it is provided with a handle atthe juncture of the two members thereof. When the upright 1 is throwndown, the rod 22 is drawn out and the handle thereon rests on the groundand supports the upright.

In the rear of the main frame is a supplemental frame 23, in which issecured a feedscrew 24, which bears against or engages with thedrill-stock and feeds it forward to make the drill work properly. Thisfeed-screw is provided with two ratchet-wheels 25 25,which havereversely-inclined teeth and arranged to operate between the piece 26and the U- shaped supplemental frame 23.

Secured on one side of the main frame is a lever 27, which is operatedby the cam-disk 12, and is provided with a pawl 28 on its upturned endand another pawl 29 on the other projecting end thereof. The pawl 28 isarranged to engage with the ratchet-wheel 25 and push the same around asthe cam 12 presses the lever 27 out, thus feeding the drillstock forwardand causing the drill to contact properly with the work on which it isoperating.

As heretofore mentioned, I have adapted my invention to be used fortightening or loosening nuts on railways or other structures, and it istherefore necessary to provide a machine which will work equallysatisfactory in both directions. With this end in view I have providedthe hook-shaped pawl 29 to engage with the reversely-inclined teeth onthe ratchet-wheel 25, andwhich. serves to rotate the feed-screw in thereverse direction when the handles 11 are turned backward. Thus thewrench 30 can be revolved forward or backward by simply reversing themovement of the handles 11, the gears 15 and 7 revolved in a reversedirection, and the pawl on the lever 27 engages with its ratchet-wheel,and by this means the wrench is revolved and fed backward, the otherpawl simply sliding over the teeth on its ratchet-wheel and beingadapted to engage with its ratchet-wheel to reverse. the wrench when thehandles are turned in an opposite direction. This con struction andarrangement of a drill and wrench in one machine will be appreciated bythose skilled in the art, as by using my machine much time will be savedand extra mechanism avoided. After the hole has been properly drilledthedrilling-bit can be quickly removed and a wrench substitutedtherefor,

and the nut may be then screwed on the bolt without loss of time.

To insure better connection between the machine and a railroad-rail, onwhich the machine is generally used, I provide a bifurcated holding-arm31, which is pivotally secured to the front of the upright 1, said arm31 having'the hooks 32 33, adapted to engage with a rail and hold themachine firm and steady. The bifurcated arm 31, having two hooks, ispreferred to a single arm and hook and to two separate arms and hooks,as by this device the two books prevent the machine from movingsid'ewise, and the single pivoted arm on the upright permits it to befolded on the upright for convenience in carrying the machine.

34 35 are suitable handles secured on the upright l for use in movingthe machine.

The operation of my machine will be readily understood from theforegoing description, as it is only necessary to adjust the drill andbifurcated arm on the rail and operate the cranks 11. After drilling thehole, if it is desired to screw anut on a belt which has been insertedin the hole a wrench is substituted for the drill, as shown, and themachine is then operated as before. hen it is desired to remove a nutfrom a bolt, the cranks are simply turned in a reverse direction and thewrench will unscrew the nut.

In Figs. V and VI, I have shown a modified construction, which consists,principally, in providing two arms or hooks 32' 33" suitably joinedtogether, and these arms extend on either side of the main frame and areloosely secured to bars or rods 36, which are secured in place by guidesor keepers 31' midway of the frame. I also bifurcate the lower portionof the foldable brace-rod 22, and the lower ends 22' are bent outwardlyand pivotally secured at said curved portions 37 to either side of therearend of the main frame, and the projecting ends are also looselyconnected with the rear ends of the side rods 36. This IIO latterconstruction is very simple and possesses practical advantages, as itwill be read ily seen that when the upright is turned down the bracewill break back and the curved ends thereof willthrow the side bars 36for ward, and therebyloosen the grip of the arms and hooks on the rail;and, again, when the arms and hooks have been placed in position on arail, the nprightremainin g in a horizontal position, when the uprightis turned to a verti-- cal position it will cause the arms and hooks tograsp the rail firmly and assume a rigid and 1 substantial position,thus facilitating the adjustment of the machine to the rail. I have alsoshown the upright l constructed partly of wood, and the lower portionthereof consisting of two pieces of iron 38, suitably fastened to thewooden upper end and the plate 2. This is a neater construction andaffords a better opportunity for attending to the working mechanism ofthe machine.

I am aware that changes in the form and proportion of parts can be madewithout departing from the spirit or sacrificing the advantages of myinvention, and I therefore reserve the right to make such changes asfall within the scope of my invention.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-
